993c387032 os: simplify deadline fluctuation tests
This applies the net package CL 365334, CL 366176, CL 372215 to the os
package.

CL 365334:

    These tests were checking for fairly narrow timing windows, but were
    running in parallel and heavily dependent on timer and goroutine
    scheduling. This change eliminates unnecessary goroutines, runs the
    tests sequentially (dramatically shortening the timeouts to reduce the
    penalty of doing so), and uses timestamp comparison instead of
    background timers to hopefully gain some robustness from monotonic
    timestamps.

    Many of the other tests from this package would benefit from similar
    simplifications, which we can apply if and when we notice flaky
    failures or want to improve the latency of running the test.

CL 366176:

    It appears that at least the OpenBSD kernel gets sloppier the longer
    the timeout we give it, up to an observed overhead of around 25%.
    Let's give it a little more than that (33%) in the comparison, and
    also increase the growth curve to match the actual observed times
    instead of exponential initial growth.

CL 372215:

    Decrease the slop everywhere else, since NetBSD and OpenBSD seem to be
    the only ones that miss by that much.

For #36108
For #50189
Fixes #50725 (we hope)

981d5947af cmd/go: include module root in package index key
The package index format includes the directory relative to the module
root. The module root for a given directory can change even if the
contents of the directory itself do not (by adding or removing a
go.mod file in some parent directory).

Thus, we need to invalidate the index for a package when its module
root location changes.

Due to mtime skew we don't index mutable packages with an mtime

64ef16e777 cmd/internal/obj/arm64: save LR and SP in one instruction for small frames
When we create a thread with signals blocked. But glibc's
pthread_sigmask doesn't really allow us to block SIGSETXID. So we
may get a signal early on before the signal stack is set. If we
get a signal on the current stack, it will clobber anything below
the SP. This CL makes it to save LR and decrement SP in a single
MOVD.W instruction for small frames, so we don't write below the
SP.

We used to use a single MOVD.W instruction before CL 379075.
CL 379075 changed to use an STP instruction to save the LR and FP,
then decrementing the SP. This CL changes it back, just this part
(epilogues and large frame prologues are unchanged). For small
frames, it is the same number of instructions either way.

This decreases the size of a "small" frame from 0x1f0 to 0xf0.
For frame sizes in between, it could benefit from using an
STP instruction instead of using the prologue for the "large"
frame case. We don't bother it for now as this is a stop-gap
solution anyway.

This only addresses the issue with small frames. Luckily, all
functions from thread entry to setting up the signal stack have
samll frames.

Other possible ideas:
- Expand the unwind info metadata, separate SP delta and the
  location of the return address, so we can express "SP is
  decremented but the return address is in the LR register". Then
  we can always create the frame first then write the LR, without
  writing anything below the SP (except the frame pointer at SP-8,
  which is minor because it doesn't really affect program
  execution).
- Set up the signal stack immediately in mstart in assembly.

For Go 1.19 we do this simple fix. We plan to do the metadata fix
in Go 1.20 ( #53609 ).

Other LR architectures are addressed in CL 413428.

Fix #53374.

0750107074 go/token: use atomics not Mutex for last file cache
Previously, FileSet would cache the last *File found by a lookup,
using a full (exclusive) mutex within FileSet.File, turning a logical
read operation into an update. This was one of the largest sources
of contention in gopls.  This change uses atomic load/store on the
'last' field without a mutex.

Also, in FileSet.AddFile, allocate the File outside the critical
section; all the other operations are typically cheap.

20760cff00 runtime: add race annotations to cbs.lock
cbs.lock protects a map. The map implementation is race instrumented
regardless of which package is it called from.

lock/unlock are not automatically race instrumented, so we can trigger
race false positives without manually annotating our lock acquire and
release.

compileCallback is used during initialization before the P is available,
at which point raceacquire will crash during a racecallback to get the
race proc. Thus we skip instrumentation until scheduler initialization
is complete.

Fixes #50249.

a6e5be0d30 cmd/go: omit build metadata that may contain system paths when -trimpath is set
CGO flag variables often include system paths for header files and
compiled libraries. The point of -trimpath is to avoid dependending on
system paths, so stamping these variables is counterproductive.

Moreover, the point of stamping build information is to improve
reproducibility. Since we don't also stamp the versions of C
compilers, headers, and libraries used in a cgo build, only the most
trivial cgo programs can be faithfully reproduced from the stamped
information.

Likewise, the -ldflags flag may include system-specific paths,
particularly if external linking is in use. For now, we omit -ldflags
entirely; however, in the future we may instead want to parse and
redact the individual flags.

Fixes #52372.

a42573c2f1 net: avoid darwin/arm64 platform bug in TestCloseWrite
On darwin_arm64, reading from a socket at the same time as the other
end is closing it will occasionally hang for 60 seconds before
returning ECONNRESET. (This is a macOS issue, not a Go issue.)

Work around this condition by adding a brief sleep before the read.

Fixes #49352 (we hope).
Updates #37795.

c3bea70d9b cmd/link: link against libsynchronization.a for -race on windows
As of LLVM rev 41cb504b7c4b18ac15830107431a0c1eec73a6b2, the
race detector runtime now refers to things in the windows
synchronization library, hence when doing windows internal
linking, at that library to the list of host archives that
we visit. The tsan code that makes the reference is here:

41cb504b7c/compiler-rt/lib/sanitizer_common/sanitizer_win.cpp (L48)
41cb504b7c/compiler-rt/lib/sanitizer_common/sanitizer_win.cpp (L834)

Note that libsynchronization.a is not guaranteed to be available on
all windows systems, so in the external linking case, check for its
existence before adding "-lsynchronization" to the external linker
args.

Updates #53539.

666d736ecb cmd/compile: do branch/label checks only once
The previous change implemented the missing fallthrough checking
in the parser. Therefore we can now disable the duplicate check
in the type checker:

- rename (types2.Config.)IngoreLabels to IgnoreBranches to more
  accurately reflect its functionality

- now also ignore break/continue/fallthroughs, not just labels

The IgnoreBranches flag only exists for types2, for use with
the compiler. There's no need to port this code to go/types.

Note: An alternative (and perhaps better) approach would be
to not use the the parser's CheckBranches mode and instead
enable (i.e. not disable) the branch/label checking in the
type checker. However, this requires a bit more work because
the type checker's error messages about goto's jumping over
variables don't have access to the variable names, which are
desired in the error messages.

Fixes #51456.

http_1_5_good behavior (about 7ms of total run time and trace file size
